SAFETY Ges-BURNER.'

Specification of Letters Patent.;

Patented Aug. 20, '1907'.

Application filed November 10.1906.. Serial No- 342.770.

To vall whom it muy concern:

Be it known that I, LUDV'IG LIUGLOF, a subject ofl the King of Sweden, residingat Newark, in the county,

of Essex and. State of New Jersey, have invented eer.- tain new and useful Improvements in Safety Gas- Burnersfand I do hereby` declare' the following-to be a fu'll, clear, and exact description of the invention, such as will-enable others skilled in the art to which` it appertains to make and use the same, reierencebe'ing had tothe accompanying drawings, and to letters of reference marked thereon, which forma part` of this specification.

of a thermostatic strip and to remain open lby. reason of theexpansion of the thermostatic strip due to the heat from the burner.. .Y A

The invention is designedv to provide a manually operated attachment for opening the` automatic valve untilhea.` is generated from the burnerg'and the device also provides a series of secondary outletsfor the gas which can allow small jets of flames to issue from them to assist in' heating the burner when the .light is belThe invention is illustrated in the accompanying drawings, in which` Figure 1 is a vertical section of a lburner of the class Y described, and Fig. 21is a similar view of a modified sliding thereon, is ai sleeve 16 having the lower? portion 17 forming a chamber for the spring 18 to normally hold the sleeve up. `A chain or similar device 18 is iastened `to the bottom of the sleeve 16, and when it is desired to light the light, this chain -is pulleddown. Whenthe sleeve 'rides down, a spring 19, fastened-to the inside oi the sleeve, which is composed of material easily expansible by the application of heat, has lower end 20 shaped so as to displace the ball 15 and allow gas to pass out through tha passage 13, and the gas escaping trom the pipe 2S can be ignited.' At the same time, when the sleeve is pulled down, the gas passes from the sleeve 16 through an'opening 21 which is provided. between the flange of the sleeve and the sleeve 12,' and the gas can thou pass out through aseries of very'sniall perforations 2" and the match, when applied to these, surrounds the sleevel' with a series of small jets vof llame which Vwill instantly heatup the sleeve 16 and the'spring 1 9, and 1 have demonstrated, by test, that -the spring 19 will expand enough withina very few seconds to maintain the .ball 15 away from Athe s eatll, alter the chain is released, and the sleeve 16 again rides up to'the position shown in Fig. 1. The

spring of course,` will then maintain the valve open,

and the light will not go out unless the gas is turned off, or if the gas is blown out, the absence of heat will contract the spring 19, 4and the end 20will be automatically withdrawn to allow .the ball 15 to seat itself.

` Fig. 2 shows a similar structure, but in place" of the ball 15 Iemploy a valve 24,tl1at has the openings 25,

this valve being'lcept close up to itsjseat by reason of ,the 'pressure of the' gas, and when it drops down the openings25, beingindented on their topedges from the outside, allow the gas to escape around the sides of the valve. In the case of a Welsbach burner, I can use the structure showngin Fig. 3 which embodies a long sleeve having a flaring. portion 2G that' is turned toV regulate theadrnission of air7 and itis provided-with a series oi'ports 27. In one oi these series of ports' 27 is hinged, as at 28, Ia lever 29 which has a'pin 30 to engage the Astraight end 20 of thespring 19, and the other end 31 of the lever has'secured thereto, a'chain 18 adapted 'to be Vmanually operated'so that'when the. chain is pulled, the pin 30 throws theend of the spring over to move the ball 15 away from, its seat. The light orA flame issuing from the gauze 32,in thexusual way, soon heats up the spring 1-9 -to hold the valve open without any manual operation .after the light-is lighted.

Having' thus described my invention, what I claim istl. A burner comprising a fixed sleeve having a seat therein. avalve on the seat, a ,thermostatic spring,.and a slid- 'ing sleeve supporting the spring, the spring being;v adapted to engage the valve to open. it when heated or whenthe sliding sleeve isoperated.

A burner comprising a fixed sleeve, a sliding sleeve on the xed sleeve, a valve in .the tlxed sleeve, a thermostatic spring` t'o operate the valve, secured to' the sliding sleeve, and means for manually'operatingthe sliding sleeve.

3. A burner comprising a fixed sleeve,`a sliding sleeve thereon, aseat on the fixed sleeve, a ball o n the seat, a\

thermostatic spring secured tothe sliding sleeve and adapt- .edto unseat the ball;

4. Q-Yburnercomprising a casing having a valve therein,

`a thermostaticj means for operating the valye, means for manually operating the thermostatic nieans,.the 'casing having gas. outlets in its sides to' be supplied with gas when the valve is manually operated.

5. A burner comprising a casing having a valve dere-in, a thermostatic spring for operating the4 valve to open it, and manually operated means for opening ,the valve', the easing having gas outlets. in itsf'sidesto be supplied'wi'th gas when the valve 4is opened manually.

6. A burner comprising a casing having a seat therein,

loo

a bullion the seat, a thermostatic spring in the casing to l unseat the ball, and means for manually operating the' ball to unseat it, the casing huvng'gas outlets near the bottom to be supplied wit1'1 ga 'when the ball is manually 5 operated. v

7. A burner comprising a fixed `sleeve, a. sleeve sliding on the fixed sleeve, a set on the fixed sleeve, a ball on the seat, athermostatic spring in the slidinf,r sleeve t'o unseat .the ball ivhexrthe sleeve is operated, and a closure between the sleeves, adapted to open when thc sliding-*sleeve is 1U manually operated, the sliding Sleeve having a series 0f gasl outlets in its sides below the closure.

In testimony, that l clz'lim the foregoing, I have here-A unto set my hund this 9th day of November 1006.
